WARNING SURFACES •D O NOT TOUCH SURFACE UNITS OR AREAS NEAR UNITS – Surface units may be hot even though they are dark in color. Areas near surface units may become hot enough to cause burns. During and after use, do not touch, or let clothing or other flammable materials contact surface units or areas near units until they have had sufficient time to cool. Among these areas are the cooktop and surfaces close to the cook-top. WARNING •D O NOT TOUCH HEATING ELEMENTS OR INTERIOR SURFACES OF OVEN – Heating elements may be hot even though they are dark in color. Interior surfaces of an oven become hot enough to cause burns. During and after use, do not touch, or let clothing or other flammable materials contact heating elements or interior surfaces of oven until they have had sufficient time to cool. Other surfaces of the appliance may become hot enough to cause burns – among these surfaces are oven vent openings and surfaces near these openings, oven doors, and windows of oven doors. WARNING To avoid risk of electrical shock, personal injury, or death, make sure your range has been properly grounded and always disconnect it from main power supply before any servicing. 1. Precaution SURFACE COOKING UNITS VENTILATING HOODS: •U se Proper Pan Size – This appliance is equipped with one or more surface units of different sizes. Select utensils having flat bottoms large enough to cover the surface unit heating element. The use of undersized utensils will expose a portion of the heating element to direct contact and may result in ignition of clothing. Proper relationship of utensil to burner will also improve efficiency. • Never Leave Surface Units Unattended at High Heat Settings – Boil overs may cause smoking and greasy spillovers may ignite. • Make Sure Reflector Pans or Drip Bowls Are in Place – Absence of these pans or bowls during cooking may subject wiring or components underneath to damage. • Protective Liners – Do not use aluminum foil to line surface unit drip bowls or oven bottoms, except as suggested in the manual. Improper installation of these liners may result in a risk of electric shock, or fire. •G lazed Cooking Utensils – Only certain types of glass, glass/ceramic, ceramic, earthenware, or other glazed utensils are suitable for range-top service without breaking due to the sudden change in temperature. • Utensil Handles Should Be Turned Inward and Not Extend Over Adjacent Surface Units – To reduce the risk of burns, ignition of flammable materials, and spillage due to unintentional contact with the utensil, the handle of a utensil should be positioned so that it is turned inward, and does not extend over adjacent surface units. •D o Not Soak Removable Heating Elements – Heating elements should never be immersed in water. • Be sure you know which control pads operate each surface unit. Make sure you turned on the correct surface unit. •C lean Ventilating Hoods Frequently – Grease should not be allowed to accumulate on hood or filter. • When flaming foods under the hood, turn the fan on. OVEN • Use Care When Opening Door – Let hot air or steam escape before you remove or replace food in the oven • Do Not Heat Unopened Food Containers – Buildup of pressure may cause container to burst and result in injury. • Keep Oven Vent Ducts Unobstructed – the oven vent is located above the left rear surface unit. this area could become hot during oven use. Never block this vent and never place plastic or heatsensitive items on vent • Placement of Oven Racks – Always place oven racks in desired location while oven is cool. If rack must be moved while oven is hot, do not let potholder contact hot heating element in oven. • Do Not allow aluminum foil or meat probe to contact heating elements. GLASS/CERAMIC COOKING SURFACES •D o Not Cook on Broken Cook-Top – If cook-top should break, cleaning solutions and spillovers may penetrate the broken cooktop and create a risk of electric shock. Contact a qualified technician immediately. • Clean Cook-Top With Caution – If a wet sponge or cloth is used to wipe spills on a hot cooking area, be careful to avoid steam burn. Some cleaners can produce noxious fumes if applied to a hot surface. DEEP FAT FRYERS: SELF-CLEAN OVENS • Use extreme caution when moving the grease kettle or disposing of hot grease. •D o Not Clean Door Gasket – The door gasket is essential for a good seal. Care should be taken not to rub, damage, or move the gasket. • Do Not Use Oven Cleaners – No commercial oven cleaner or oven liner protective coating of any kind should be used in or around any part of the oven. • Clean in the self-clean cycle only parts listed in this manual. Before self-cleaning the oven, remove the broiler pan and any utensils from the oven. •N ever keep pet birds in the kitchen – the health of birds is extremely sensitive to the fumes released during an oven selfclean cycle. Fumes may be harmful or fatal to birds.
